Subject: [PATCH v14 2/6] of/platform: Add stubs for of_platform_device_create/destroy()
Date: Mon, 19 Jul 2021 15:21:24 -0700	[thread overview]
Message-ID: <20210719152055.v14.2.I08fd2e1c775af04f663730e9fb4d00e6bbb38541@changeid> (raw)
In-Reply-To: <20210719222128.4122837-1-mka@chromium.org>

Code for platform_device_create() and of_platform_device_destroy() is
only generated if CONFIG_OF_ADDRESS=y. Add stubs to avoid unresolved
symbols when CONFIG_OF_ADDRESS is not set.
